My invention relates generally to improvements in spreaders'orplows but relates more particularly to improvement-sin Spreaders or plows-for use in conjunction with roadve- 5* hides; and has t'or its object the'distribution, spreading and 'shapin'gof anymaterial that "11'l2l y"b6 upon the roadway and themovement 'of'which it is desired to elf'ect. In them'aking of 'roads. or in the maintenance thereof it is often desirable' to be able. to level or "spread materialpreviously. deposited upon-the road toth'e .end' that .a desired levelpor grad'e of the road may be" secured. Also in "making new roadways it is often'necessary to remove material that is above the desiredgrade' at one side of the roadway to the" opposite side or some intermediate point 'where' theroad- Way may be below the desired grade or level. In the course of making a new roadway considerable difficulty has heretofore been encountered in maintaining the desired grade.

,That is to-say, assuming that the course ot "the proposed. road undulates, 1. e. 1s rough and irregular, at 1S necessaryv to remove varymg amounts of material. Because of'this, "fact and also because .01? theit'act that in machines heretofore devised for 'thispurpose the material moving means found'its'support "intermediate the ground contacting "wheels or tractive elements of the vehicle,- the course of movement of the material moving means did not proceed along any fixed grade or plane, but usually'tollow-ed some mean line between the forward and rearward support ing elements, thus'requiringseveral operations in order to remove accurately to grade.

1111 road maintenance work it is also im- "perative that means shall'be at :handrwhereb-y itrafiic .soon compacts the snow to suchanextent as to baflle removal except bysu'ch slow and laborious a method as with picka-Xe and shovel.

Whileit is necessary that those in charge I ofhighway maintenance shall be prepared .for the. removal of snow it maybe; that "*weatherponditions 'are su'ch that little, if any, snowfalls; thus necessitating use but a few-times during the year and during some winters not at all. "Asa-result it has heretoiore been-necessarytdmake a heavy investment insm'ac'hinesthe use of which was reguired'only'at very infrequent periods.

Trhe general objectotmyinvent ion is to iltiis ia "further obj ect of 'my invention to provide 'af fplownnd spreader whichzshall be capable of shiftin'gor conveying material from 'a considerable distance on one side .of -'?the roadfto-a considerable distance :upon the other with the-resultant ability to shift maiterialandlevel'a considerable expanse of. :roadway in oneroperation "while in use as a "roaid"building'pdevice, and-with the ability to 'clearpractically'anentire roadway of snow in ".arsing'l'eimove'ment' or'passage thereover when need-tori snow removal purposes.

'a'c'ter mentioned .which shall be capable of easy attachmenti to andtremoval from the "roadyehicle or .devicewhich is to propel the 'same,".or to. whichit is to be attached.

A "furtherxobject of my invention is to pro- 'vide adevi'ce: of the character mentioned wlhicli shallbe OfASLlCh construction as to be 'easijly operated; which shall be composed of 'relativelyffew parts; and which shall be .so

formed and constructed as easily to withstand the forces. to which it is. subjected in use and hence whlichwi'll be .ot durable character.

invention consists generally inapparatus ofthe form, arrangement, construction, and co-operation of the parts whereby the above named objects, together with others that will appearhereinafter, are attainable;

an'duny invention will be more readily understoo'd'by reference'to the accompanying drawings which illustrate what'I consider,

,at'the present time, to bethe preferred 1em-.

bodied in the appended claims. ,I wish it to be understood, however, that my apparatus,

in many respects, functions better when tached to a tractor'having elongated endless tractor elements. .Z For instance, in themoving or displacing of heavymaterials, or large: amounts of materials, or materials that are I I I tbracedat the nose by means of the angle memtractivesurface of the endless tractive eleinents and the great tractive effort which is; thereby attainable, enables the removal and displacement of materials i i/amounts and in character which would otherwise completely bafliedisplacement. -So, also, the making of a roadway the endlesstractor-elements are.

of especial value inasmuch as they serve as a support rearward of the phi-wand Fhence upon the previously smoothed or leveled part of the roadway. Because of thelextended character.

of the support it, is, also possible to cut or remove large amounts of mater al without-cans ing the plow to dig itself downwardly below the grade or level which it is desired to maintam. Thus, it becames apparent that my apparatus is of especialvalue when used 111 conjunction with a tractor of the endless tread type and for this'reason Ihave designedv the apparatus here shown so that it may be very easily as well as very quickly attached to a machine .of that type.;

Referring now to the drawings for the details of construction 1 and 2 representthe I "endless tractor elements and 3 the frame of the tractor, all being ind cated by means of I 1 straddle the ll-beams and that t ey dotted lines better to display the construcworking position. I I .mounting the beam 16 at such height that l7, 18, 19 and 20 and here shown, my apparatus likewise is built upon or around a frame. The frame, in this instance, is composed of the parallel side members 4 and 5, respectively, which assume I the form of channel members and which at Fig. 4 is a fragmentary View of one of the.-

their forward ends are bent inwardly at an angle to form the portions 6 and 7, respectively. The frame portions 6 and. 7 are rigidly conn'ecte'drby. the transverse channel member-:8- andthe rear ends of the side channels i and 5 are cross-connected by means of an-anglemember 9 which, in turn, is'bolted or otherwise rigidly secured to the frame 3 of the tractor as by'm'eans'of bolts 10'.

Theframe is also cross-connected near the front end by means of the channel member 11 which is pressed orhumped upwardly in the middle so that it may pass on the upper sidev of the front portion I o of the tractor frame. In fact, it rests upon the tractor frame, being suitably secured thereto by means. of bolts. Thus, it Wlll be observed I I .that the frame .ofinyapparatus encompasses the tractor and that ,it is supportedftherefrom'by the transversebrace memberswhich serve rigidly to hold the frame. of my apparatus 1n place. In order that there may be Inoconfusiou, I shall hereinafter refer to the ber'15 and rearwa-rdly are cross-connected means of the beam 16. This beanr 16 serves a dual purpose, to wit, that of brae ing the -plates 13 and islcf the plowand also of supporting the plow in ts lowermost This is accomplished by when the-plow 1:2 is in itslowermost workposition: the beam 16 will rest upon the upper face-s ofthe portions 6 and '1' of the plow spreaderframe. For venous purposes and for different reasons it is necessary or at least'desirable that the plow shallbe '-.'er-

tically movable and, at the same time, due to the enormous forces encountered in 'ac 1.tiou,'it must be Very rigidly an d; substantially mounted.

A strap 63 secured to the I-beam 60, encompasses the channel members 58 and 59 and serves to take most of the strain off the securing bolts 62. The channel members 58 and 59,

at their lower ends,- straddle the spreader wing 35 and are-secured thereto by. means of the horizontal pivot 64. Thus the spreader wing 35 is mounted for vertical movement as v a whole upwardly or downwardly, sliding on the vertical I-beam. It may likewise, as before described, be swung upon the lllZ011 tal pivot 51 to position its lower edge at any desired angle to the horizontal, being held very'firmly'and securely many of its placed positions'by' means of the diagonal strut orwingpressing member 55. "It will be understood, also,'that the spreader wing maybe swung to and from'the side of the apparatus swinging upon 1 the vertical pivot 52. F or bracing and holding'thespreaderwing in desiredangular position relative to the side of the plowspreader frame I have provided a" plurality of adjustable braces 65, which are of diiferentlengths, but are otherwise similar in construction. Therefore, a description of one will suffice for all. As is probably best shown in Figs. 6 and 7, the brace 65 is'com-- posed of a centralhollow tubular member 66 into which extend the solid end members-67 and 68. The members 67 and 68, at their outer ends, are bifurcated and straddle respectively the angle member 69 secured to the inner side of the spreader wing 35, and the angle member 70 which is secured to the plow sp1'eader' frame, being secured to the said parts by means ofthe bolts 71 and 72 respec- 'tively. The tubular member 66 is sufficiently large to admit the members 67 and 68 freely that telescoping'of the parts may .take I place in order to change the effectivelength' of the brace 65. For holding the parts-in any set position I provide the members 67 and 68 with a 'plurality of vertical holes 73 and '54, respectively and provide the tubular member 66 with correspondinglysized holes By aligning these holes and fastening bolts 'Z6and 77 therethrough. the parts are locked in, any set position. If it is desired to swing the spreader wing 35 into substantially parallel relation to the plow spreader frame the braces "65 may be very quickly and easily removed, v

At times it may be desirable'to sh ft or move material from a point-beyond the cen-.

ter of the apparatus to a point considerably to one side thereof and for'this purpose I have provided what I term a. front wing and which bears the reference character 78. L This observed that I provide a cable 81 which is attached at one'end to the crossbeam 16 of the hand lever 87 which carries the pawl88 for engagement with the ratchet portion89 a of the drum. By this means a very powerful pull canbe exerted upon the cable 81 serving to lift the plow. iAs before stated, however, before the plowcan be-raised-it-is necessary to break the toggle brace, as before described. Of 1 course,'. reversal of the drum permitsthe plow to move downwardly which it will do of its. own weight.

The'sprea'der' wings 35 and 36 maybe raised by means of similar drums 90 and 91 which are actuated byratchet levers of'the iou construction already described, The cable 92 has oneend attached to the hinged portion" 54 of the? mounting means for the spreaderwing' 35, passes over the horizontally disposed sheave 93, and thence to the drumi90. "A cable 94 similarlypasses another sheave 95 and thence to the other side of the apparatus where it is connected, in the same manner,'to the means supporting the wing 36 and likewise has one'end secured to the drum 91. The various drums 85,90

and 91 are arranged in close proximity, one

to the other, so that they mayall be manipulated, conveniently, from one position on the vehicle;- I 1 I omitted tostate that the cross member 86 is supported by the'standards 96 which upstand from the plow spreader frame member and also by means of the :braces97 that extend rearwardly from the upper cross channel member 42. I v

' It will" be understood that the apparatus may be used either with or without the front spreader wing; Also that the spreader wing may be reversed so as to extend-in the position opposite from that shown in full "lines in the drawing, the full line position being a position-in which it is placed Whenit cooperates with the wing 35. S0 also-it should be understood that the spreader wings may both be used at the same time in conjunction with the front plow, or one thereof may be used in conjunction with the front plow, or both of the wings may be swung to inoperative position at the side of the plow spreader frame and the plow alone employed.

Again, if desired, the plow and the front wing may be used together. From the foregoing it will be observed that the objects set forth in the opening of the specification are fully and completely attainable by means of the apparatus herein shown and described and it will be understood that my apparatus is capable of use for a wide variety of purposes for all of which it serves in an admirable manner.

By removing the rear cross brace 9, and removing the bolts that secure the front brace 11 to the frame of the tractor my apparatus can be bodily removed from the tractor. Of course the attachment of my apparatus to the tractor is eflected by a mere reversal of the steps described.

Inasmuch as this disclosure will suggest to others skilled in the art to which this appertains modified constructions whereby the substantial objects and purposes may be attained, I do not wish to be limited to the specific construction herein shown and described, except only as may be necessary by limitations in the hereunto appended claims.
